Preheat a grill to medium.
Brush the sliced bread with pesto and grill until slightly charred. Remove the bread from the grill, cut it into 1-inch cubes and add it to a serving bowl. Gently stir in the tomatoes, cheese curds, and the mixed greens.
Vinaigrette: Add the vinegar, mustard, shallot, garlic, thyme, marjoram, oregano, olive oil and salt and pepper, to taste, to a food processor. Pulse to combine. Pour the vinaigrette over the salad let it soak into the bread for 20 minutes before serving.
